Pull request overview

This pull request updates the editor Undo/Redo behavior and related UI test documentation to align with Gutenberg’s granular history, while also improving accessibility and preserving history availability when editor modals are shown/hidden.

Changes:

• Switch Undo/Redo disabled handling from isUserInteractionEnabled to isEnabled so disabled state is exposed to accessibility (VoiceOver).
• In NewGutenbergViewController, preserve undo/redo availability across modal open/close by tracking history-disabled state separately from general navigation-item enabled state.
• Update the AI agent UI test steps to account for granular undo/redo history (multiple taps may be required).
